Diagnosis Details 

Conditions for illuminating the MIL 

When a malfunction is detected during the first drive cycle, a Temporary DTC is stored in the PCM 
memory. If the malfunction recurs during the next (second) drive cycle, the MIL comes on and the DTC and 
the freeze frame data are stored. 

Conditions for clearing the MIL 

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the 
diagnostic runs. 

The MIL, the DTC, the Temporary DTC, and the freeze frame data can be cleared by using the scan tool 
Clear command or by disconnecting the battery.

Fig. 174: Transmission Gear Shift Selection Position 

General Description 

When the shift lever is moved to the M position (the sequential sportshift mode (S-MODE) is selected), the 
upshift (S-UP) switch and the downshift (S-DN) switch can be used. When the shift lever is moved toward 
the S-UP switch, an upshift is executed, and when the shift lever is moved toward the S-DN switch, a 
downshift is executed. The S-MODE switch signal, the S-UP switch signal, and the S-DN switch signal are 
grounded when turned on and opened when turned off. 

When the S-UP switch is turned on in the P, R, N, and D3 positions, a malfunction of the S-UP switch is 
detected and a DTC is stored.
